Question

Solve for x: 2x+4=16

Answer 1

Answer: x = 6

Step-by-step explanation: To solve for x, we must first

isolate the term containing x, which in this problem is 2x.

Since 4 is being added to 2x, we subtract 4

from both sides of the equation to isolate the 2x.

On the left, the +4 and -4 cancels

out and on the right, 16 - 4 is 12.

So we have 2x = 12.

Then just divide both sides by 2 so x = 6.

Answer 2

Answer:

6

Step-by-step explanation:

2x+4=16

2x=12
